  1. Hello everyone, thanks for approving me! <3 I was searching as a guest last night for answers, but i was unsuccesful.. If a thread with this question already exists, PLEASE point me to it so i can educate myself. I also tried to ask a few questions on the Growdiaries site, but that limits you to 280 Characters and that is not even remotely enough to explain the (ill call it mini problem) im having. I am 9 weeks into my very first grow. After some extensive research on ADHD, I chose one of the exotics, a landrace heirloom sativa, Dr. Grinspoon as the one i want to grow, thinking the end result will help my other half to be motivated and productive during the day. (But thats not the question.) Following all Advanced Nutrients calculators online and guide sites specifically made for Advanced nutrients and growing in coco. The recommended amounts per litre are somewhat reasonable when you look at them, i mean its only reasonable to have 4ml A&B per litre of water during late flower right? Well my TDS pen says otherwise. From what ive gathered, Early seedlings like to be at a range of 300-500EC Early and mid veg it likes to be at a range of 1.1-1.5 and early and late bloom it likes to sit at 1.7-2 (average numbers ive gathered over many different sites and forums) That is understandable and easy to follow. The problem comes here: Even though i am on week 9, because of some complications dring early seedling phase, my Dr.G didnt develop very fast, so i am currently using nute strength for week 3 of veg. The recommended amount of nutes at this stage is 3ml(A&B) of sensi grow and 1.5ml of vitamin-B52 per litre. That brings my 1 litre of water all the way up to 2.2 and im not even at full recommended dosage, or not yet using any supplements that ill have to be using during flowering. That panicks me a little and i dont really want to give that to my G as i already stressed it plenty during early veg with transplanting it into a massive pot with poor drainage. What i do is, i add all the recommended amounts, and then i add 250ml of extra bottled water (using still bottled water from the supermarket that reads at 0.18) to bring the EC down to 1.7-1.9 which Doc seems to be okay with. My question is: Is this right? i mean when i add that 250ml extra water to dilute the feed, the recommended measurements stop being per litre and begin being per 1.25 litre. Is that right thing to do? what happens when i reach full recommended strength and it skyrockets the EC all the way up to 3 (and i know it will considering the nubers im having right now). Do i still keep diluting it with more fresh water until i reach the recommended EC? Or do i keep the feed measurements at 1 litre ignoring the EC levels? I already burned the plant when i had the poor drainage situation and the EC rose up to 5 and i had to transplant it to fresh medium so it wouldnt continue dying. Doesnt diluting the feed made with the recommended amounts also lowers the strength, making the feed weaker than what is the recommended? Any Info would be very much appreciated, and again, i was searching all night to find this answer, and its been bothering me for the last few weeks, If an answer or a similar topic exists already and i missed it PLEASE point me to it so i can read and gather info Thanks for reading and sorry if its too long.
